The 6.1 95s don't have a 16 X 19 pattern, they have 16 X 18 or, as you know, 18 X 20. Personally, I found the 18 X 20 to be hugely more accurate than the 16 X 18, which to me, performed poorly compared to other player's 16 X 18 or 19 frames. (Of course, that's just my experience).
You've got to decide if other aspects of your game are enhanced enough to outweigh that lack of control.
